HEATING-DRUM.

SPECIFICATIONformng partofnLetters Patent No. 608,935, dated August 9, 1898. Application filed August 2,6, 1897. Serial No. 649,696.` `(No model.)

To all whom t may concern:

Be it known that I, CHARLES P, VERNIER, of Butler, in the county of De Kalb and State of Indiana, have invented certain new and use- `ful Improvements in Heating-Drums; and I do hereby declare the followinglto be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in heating apparatus, and has more particular relation to heating-drums.

The invention consists of certain novel constructions, combinations, and arrangements of parts, all of which will be hereinafter more particularly set forth and claimed.

In the accompanying drawings,forming part of this specification, Figure l represents a side elevation of the device embodying my invention. Fig. 2 represents a centralvertical section through thesame. Fig. 3 represents an enlarged detail perspective view of the partitions or wings, and Fig. 4 represents an enlarged detail perspective view of one of the dampers.

l in the drawings represents the casing of my improved device; 2 2, the top and bottom caps of the same; 3 3, the heating-pipes; 4L, the partition, and 5 5 the dampers. Said casing 1 is preferably cylindrical, as shown in the drawings, and is provided with two heads or caps 2 2, which close, respectively, the upper and lower ends of said casing and are provided with annular flanges 6 6 for the application of the device to the usual-sized stovepipe. Said heating-tubes 3 are preferably three in number and extend from the top to the bottom of the casing l, having communication at each end with the exterior of said casing through suitable apertures formed therein. The partition 4, which is adapted to divide the interior casingl into three segmental compartments, comprises three wings or plates 7, 8, and 9, suitably secured together and to the interior of the casing l, so as to include one of the pipes 3 in each chamber formed by said wings.V The wing 7 is of full length; but the wings 8 and 9 are cut away, respectively, at the top and bottom, as at l0 and ll, for a purpose hereinafter more particularly set forth.

Each of the dampers 5 is of the peculiar segmental form shown in the drawings and is provided upon diametrically opposite sides with a trunnion l2 and a crank-handle 13, said trunnion and handle being journaled in oppositeA sides ofthe casing 1, so that the damper mayflbe tipped to open or close the passage through the casing l. The upper damper is arranged so as to close the cham bers between the partitions 7 `and 9 and 8 and 9, but leaves the chambers between the partitions 7 and 8 open, while the damper at the bottom of the casingV is arranged to close the chambers between the partitions 7 and 8and 8 and 9, leaving that between the partitions 7 and 9 open. When the dampers are closed, the smoke and other products ofcoinbustion passing up from the stovepipe enters the casing l in the chamber formed between the wings 7 and 8 and passes upward and through the recess portion ll of the wing 8. It then passes downwardinto the chamber between the .Wings 8 and 9 and through the recess lO, thence u pward between the wings 7 and 9 andmoutat the top of the casing. By this peculiar tortuous passage of the smoke and products of combustion the same are brought into very intimate contact with all of the heating-tubes 3, the heated air within said tubes passing out of the casing at the upper openings, while the cold air to be heated is drawn into said tubes through the openings at the bottom of the casing. In order to hold the damper in position when closed, I form the tops of the partitions 7 and S andthe bottoms of the partitions 7 and 9 with lateral iianges 14, under which the edges of said dampers rest when closed. Vthen so desired, both of the dampers may be opened, and thus permit the products of combustion to pass upward freely through the casing l.

By my improved device the rooms of dwell ings may be readily heated by simply inserting one of my improved drums into the stovepipe passing therethrough. The degree of heat required may also be regulated at will by simply opening and closing the dampers to a greater or less degree.

I-Iaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

IOD

l. In a heatingdrum,the combination with the drum proper, of air-heating tubes enh tendingthrough the same and opening laterally through said drum at top and bottom, and vertical radial partitions in said drum, arranged one on each side of each tube and having openings alternately at top and bottom for causing the products of combustion to follow a tortuous passage, substantially as described.

2. In a heating-drum, the combination with the drum proper, of air tubes extending through the same and opening laterally at each end through said drum, radiating vertical partitions in said drum cut away alternately at top and bottom to form passages whereby the products of combustion pass up into a chamber between two of said partitions, as 7 and 8, over 8 and down through an adjoining chamber between the last-named and the adjoining partition and under the lat ter, whereby the heat and products of combustion are brought into contact with the airtubes in said chambers, and dampers arranged to control the passage of the products of combustion, substantially as described.

3. In a heating-dru1n, the combination with the drum proper, of air-tubes mounted in the same and opening laterally at top and bottom through said drum, a plurality of radiating vertical partitions within said drum arranged to embrace an air-tube between each pair, and formed to cause the smoke and products of combustion to follow a tortuous passage through the chambers formed by said radial partitions, and pivoted dampers above and below said partitions arranged to close each a portion of the chambers formed by said partitions, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.`
